Deadline has word that a possible spinoff of "Arrow" and "The Flash" is in development at The CW -- one that could unite several recurring characters from both shows. Brandon Routh (The Atom on "Arrow"), Victor Garber (one-half of Firestorm on "The Flash"), Wentworth Miller (the villainous Captain Cold on "The Flash") and Caity Lotz (Canary on "Arrow") are expected to star, and the potential show is reported to also feature "three major DC Comics characters who have never appeared in a TV series."

“THE TRAVELER” | Described as a “Han Solo-esque rogue who gets by with his charm, this hero hails from the future, and has journeyed back in time on a secret mission. His razor-sharp wit hides the pain of a man who has lived through serious conflict. He also harbors many secrets, always leaving both his teammates and the audience unsure of his true allegiances.

“FEMALE WARRIOR” | This twentysomething Latina is pretty but unassuming, book smart and socially awkward by day. But by night, when she hears the cry of battle, her fury is ignited and she becomes a fierce warrior — so much so, that sometimes she can become a threat to others.

“MYSTERY HERO” | An African-American male in his twenties will fill the role of a regular, street smart guy who unexpectedly gains powers, and then, as part of the team, regularly quips about the insanity of the situations.

Guesses as to who the characters could be at the link.

Use of the words "the team" and "teammates" confirms this is, in fact, a show about a regular team line-up. A lot of people were speculating this would be an anthology of short arcs featuring rotating pairs of characters teaming up, for some reason, despite the original announcement and subsequent comments from cast and producers making it pretty obvious that that was not the case.
